"Mir, Ubuntu's in-progress replacement for the X Window System, is being used internally at Ubuntu developer Canonical and will be available to all users in the next version of the operating system. Mir was announced in March, with Canonical saying that a new display server is needed to power the Unity interface across desktops, phones, and tablets." Anyone here experience with Mir? Is it any good? any downsides?

big campaign about being friendly, community etc and tbh I think we know it is all bullshit

Sorry, how is it "all bullshit"? Maybe Mir will crash and burn, maybe it won't but at least they tried to move forward.

There's this rather strange sentiment in some parts of the Linux community; on one hand Canonical is not innovative enough and doesn't have enough own projects but on the other hand they have all these own projects that splits the community , causes fragmentation etc etc yadyadayada.
Damned if you do, damned if you don't. The peanut gallery is in full effect.

At least they're not trying to force their choice onto everyone else (ala RedHat with systemd, among other things).
